In recent years sexualised drug use, usually referred to as chemsex, has become the object of intense media health‐related panic and increasing academic scrutiny. Critical social scientists have challenged pathologising perspectives, analysing the socio‐cultural and political economy dimensions of chemsex. Against the silence of geographers in this emerging field, the paper develops a geographical relational analysis of chemsex, focusing on the experiences of gay men living with HIV in two Italian cities (Bologna; Milan) and Italian gay men living with HIV in three English cities (Leicester; London; Manchester). Demonstrating the constitutive role of place in the practice of chemsex, the paper frames place relationally, that is, as the encounter between here and there, the material and the virtual, imagined geographies and lived spaces. To emphasise the central role of place and geographical knowledge to understand chemsex, the paper builds on 'weak theory', as it conceives things as open, entangled, connected and in flux, while focusing on ordinary practices and heterogeneity in more‐than‐human worlds. Showing how chemsex represents an embodied, relational geographical encounter among different human and non‐human actors, places (both physical and digital), imaginations and desires, the paper highlights the role of sexual practices in the relational construction of place‐making, therefore calling for an increased engagement with sex itself within the field of geographies of sexualities. The paper introduces a relational geographical perspective to the analysis of chemsex. Demonstrating the constitutive role of place in the practice of chemsex, the paper frames place relationally, i.e. as the encounter between here and there, the material and the virtual, imagined geographies and lived spaces. The paper calls for an increased engagement with the materiality of sex within the field of geographies of sexualities. [ABSTRACT FROM AUTHOR]

The purpose of this paper is to consider the possibility of the adaptive reuse of former Italian penitentiary buildings as tourist accommodation. This paper is a practitioner viewpoint paper, therefore it is not based on any particular methodological approach. It describes the project launched by the Agenzia del Demanio of Italy (State Property Agency) for the transformation and redevelopment of public real estate; it analyzes some international and domestic cases of former prisons' being changed over to tourist accommodation facilities. The paper identifies three methods for adapting former penitentiaries to tourist purposes: Italy has been characterized mostly by the recovery of the islands hosting abandoned prisons as preserved natural areas, while less frequent is the changeover of former penitentiaries located in urban areas, or in historical and cultural sites. The paper seeks to highlight some possibilities of adaptive reuse of former prisons, which seem not to have been fully exploited in Italy. The project by Agenzia del Demanio might be the appropriate tool to this aim, especially if more specifically focused. [ABSTRACT FROM AUTHOR]

Promoting the shift from private cars to micromobility (e.g., bike, e-bike, scooter) can represent a valuable action to improve city sustainability and liveability. Micromobility can help to replace trips by individual private cars (e.g., daily short round trips) as well as to improve coverage and accessibility of transit services, and, subsequently, to reduce the traffic impacts (e.g., pollutant emissions). It can be seen as a potential solution to move people more efficiently in urban areas, as well as to push people towards a more active mobility behaviour, contributing to the well-being goals. In this context, the paper, rather than inferring the users' propensity to change their travel mode, proposes a methodology to identify car trips that can be considered the most compatible with micromobility. Estimation of the potential demand (e.g., the upper level of car trips that could be replaced by micromobility) is carried out by exploiting the opportunity offered by floating car data (FCD) for characterising car trips. Its goodness is therefore evaluated through an application to a real case study (i.e., the city of Trani, Apulia Region, Southern Italy), divided into seventy traffic zones, and where a FCD dataset of about 5,200 trips was available. The FCD allowed the car trips to be characterised (e.g., origin and destination, path features) instead of using the traditional surveys. The results indicate that a significant share of daily car trips can be substituted (i.e., the most compatible) by micromobility (31% of car round trips in the case study), with considerable potential environmental gains (traffic emission reduction; less than 21% of total emissions from private cars). Results can be of interest to local authorities in integrating micromobility in urban mobility planning and promoting new sustainable transport alternatives, as well as to transport companies for designing new appeal services. The developed methodology is parametric and uses easy-to-obtain data available worldwide; thus, it can be easily transferred to other city contexts. [ABSTRACT FROM AUTHOR]

Freedom of Information (FOI) is considered a crown jewel of reforms fostering public administration transparency and accountability. However, FOI's symbolic power alone cannot overcome the organizational barriers and obstacles to its effective implementation. This paper presents the results of a field experiment performed in Italy, a late FOI adopter, where an FOI request was sent to the 307 municipalities with more than 30k inhabitants. The experimental design exploits marginal wording variation in the requests to test whether municipalities discriminate between ordinary citizens and high-profile requesters. The experimental evidence suggests that most Italian municipalities reply to FOI requests. The results show two opposite types of discretionary bias: Northern municipalities tend to favor high-profile requesters, whereas Southern municipalities tend to respond to them with a higher degree of attrition. The study investigates the determinants of this difference. [ABSTRACT FROM AUTHOR]

SMART cities , *CITIES & towns , *TRAFFIC congestion , *GEOGRAPHIC information systems , *LEGACY systems - Abstract
Due to increasing urbanization, nowadays, cities are facing challenges spanning multiple domains such as mobility, energy, environment, etc. For example, to reduce traffic congestion, energy consumption, and excessive pollution, big data gathered from legacy systems (e.g., sensors not conformant with modern standards), geographic information systems, gateways of public administrations, and Internet of Things technologies can be exploited to provide insights to assess the current status of a city. Moreover, the possibility to perform what-if analyses is fundamental to analyzing the impact of possible changes in the urban environment. The few available solutions for scenario definitions and analyses are limited to addressing a single domain and providing proprietary formats and tools, with scarce flexibility. Therefore, in this paper, we present a novel scenario model and editor integrated into the open-source Snap4City.org platform to enable several processing and what-if analyses in multiple domains. Different from state-of-the-art software, the proposed solution responds to a series of identified requirements, implements NGSIv2-compliant data models with formal descriptions of the urban context, and a scenario versioning method. Moreover, it allows us to carry out analyses on different domains, as shown with some examples. As a case study, a traffic congestion analysis is provided, confirming the validity and usefulness of the proposed solution. This work was developed in the context of CN MOST, the National Center on Sustainable Mobility in Italy, and for the Tourismo EC project. [ABSTRACT FROM AUTHOR]

The electrification of transport is expected to progressively replace significant shares of light duty mobility, especially in large cities. The European Alternative Fuel Infrastructure Regulation (AFIR) aims to drive the adoption of electric mobility by establishing specific targets for charging point deployment. Innovative charging concepts may complement and accelerate the uptake of this fundamental part of the urban mobility transition. In this paper, one such innovative concept is described and its potential impact is assessed. The core idea involves integrating charging points into existing city tramway infrastructures. Turin's tramway network is taken as a representative case study. The proposed technical solution encompasses a charging hub powered by four isolated DC/DC converters of 50 kW, directly connected to the DC tramway distribution line. Three of these constitute the heart of a 150 kW charger, while the fourth acts as voltage regulator. This native DC installation greatly simplifies the architecture of the DC chargers. Using a conservative approach, it was estimated that a single recharging station could charge more than 60 vehicles daily. This highly scalable and replicable solution, with the potential for over 100 conversion substations across Italy, would enable the installation of numerous high-power chargers in urban settings. Furthermore, additional benefits could be realized through enhanced recovery of kinetic energy from trams, which is currently dissipated on-board. [ABSTRACT FROM AUTHOR]

The pervasiveness of advanced technologies and their disruptive impact on society have spurred the debate on the emergence of a new industrial revolution and on its positive and negative effects, both at an individual and spatial level. This paper aims to contribute to this debate, focusing attention on the perception of changes related to the Fourth Industrial Revolution and exploring new methods of analysis of the manifestations of both techno‐enthusiasm and opposition to it. Starting from the extensive literature in this field, the work adopts two research perspectives: the study of imaginaries and narratives developed around the Fourth Industrial Revolution, which convey different messages from social groups and places; the geographies of opportunity and discontent, which address the resentment expressed by some localities towards advanced technological models and growing inequalities. In this work the Fourth Industrial Revolution is not interpreted through data about the technological variables or interviews to protagonists of the phenomenon; rather, emphasis is on the points of view of non‐institutional subjects and, in particular, the opinions expressed by people on the Web. For this reason, the sentiment analysis has been adopted to identify both positive and negative polarities and the relevance of specific feelings through the selection of key words related to the notion of the Fourth Industrial Revolution. The empirical analysis based on this methodology focuses on the Italian case in a specific period (first and second phase of the pandemic, from January 2020 to September 2021) and, at a local level, on the comparison between four medium‐sized cities (Pisa, Lecce, Taranto and Terni). This paper also tries to extend recent contributions through the provision of new perspectives for the definition of policies designed with the involvement of the population and places regarding both the processes of technological change and the definition of new socio‐spatial models.

The transformations that have taken place in the social and productive structures of economically advanced countries are to be correlated to a new structure of urban networks and territorial relations, from which it results that a vast series of activities and functions are to be considered no longer subject to localization constraints and thresholds dimensional. From this emerges a wider territorial participation in the development process, which ends up affecting the regional articulation, giving rise to the formation of reticular spatial structures [1]. It comes out the idea of sustainable mobility was than born, which was based on giving a greater role to public transport, pedestrian and bicycle movements, which are much more efficient, thanks to which you can in turn reduce time waste, pollutant emissions and increase safety at urban areas without limiting mobility. In light of these aspects, in this paper we highlight, in parallel, what has been achieved with a view to sustainability in two realities: Brindisi, a city in southern Italy, and Cracow, a Polish city. They are two realities that highlight what has been done and what are the indications coming from the stakeholders. It is possible to move in this direction for future planning and for the adoption of sustainable mobility plans adhering to territorial needs. [ABSTRACT FROM AUTHOR]

With a rising globalization of the economy and society, the digital transformation, and the economic downturn started in 2008, working is becoming less dependent on distance, location, and time. These are some of the reasons that have fostered the development and diffusion of new working spaces like coworking spaces. The paper aims at exploring the location determinants of coworking spaces, an issue that has been less developed by the literature up to now. By focusing on the 549 coworking spaces located in Italy at the year 2018, the paper investigates the location factors of such workplaces, and the attractiveness of large cities as well as peripheral areas. The results of the descriptive statistics and the econometric analysis (a Zero-Inflated Negative Binomial model is applied) confirm that coworking is mainly an urban phenomenon, since coworking spaces tend to be knowledge-intensive places for creative people. Specifically, the municipalities showing higher innovation and entrepreneurial environment (i.e. major cities) are preferred locations. Besides, it is discussed whether coworking spaces may contribute to fostering the development of peripheral and inner areas in Italy, especially during the Covid-19 pandemic where the share of teleworkers outside metropolitan areas has massively increased.

The aim of the paper is to provide an empirical framework of the ageing process in Italy, with a focus on aging in place and mobility behaviour of the elderly, as emerging from two national surveys: the “Aspects of Daily Life” survey by ISTAT and the ISFORT mobility survey. Results show that the Italian cities and towns are sufficiently age-friendly, with some improvement opportunities to be implemented. Loneliness and isolation represent a warning sign, hindering the aging in place. Finally, the study confirms that the Italian older adults use public transport only a few times, in favour of private cars. [ABSTRACT FROM AUTHOR]

For new buildings in densely urbanised cities, groundwater heat pump systems (GWHPs) represent a concrete, effective solution for decarbonising existing energy systems. Environmental factors must be considered to limit the GWHP system's impact on the subsurface. Particular attention must be given to the long-term sustainability of groundwater abstraction modalities and the development of a thermally affected zone around re-injection wells. Simplified solutions and numerical models have been applied to predict subsurface heat transport mechanisms; these simulations allow researchers to consider site-specific geological conditions, transient heat and groundwater flow regimes, and anisotropies in the subsurface media. This paper presents a comprehensive overview of the current research on GWHPs and discusses the benefits and limitations of their diffusion in Italy. The sources used provide information on and examples of the correct methodological approaches for depicting the induced variations while avoiding the overestimation or underestimation of the impact that GWHPs have on exploited aquifers.

Simple Summary: The red palm weevil beetle (Rhynchophorus ferrugineus), native to Asia, has assumed highly invasive behavior in the Mediterranean Sea basin, causing great damage to both date crops and ornamental plants. Given the lack of natural antagonists here, chemical substances must be administered to prevent attacks or cure infested palms. Through a multidisciplinary approach, we analyzed the evolution of the distribution of this beetle in San Benedetto del Tronto, a coastal city in central Italy rich in Canary Island date palms, considering both the control strategies used and their potentially negative effects. We observed that this beetle drastically reduced the palm stock by about half over the course of the 15 years between its arrival and the study's conclusion in 2020. The local municipality's program of chemical treatments has been very effective against new palm tree attacks but is expensive and poses toxicity risks for insects, animals, and the environment. However, currently, these treatments are the only effective tool for preserving the cultural landscape of this area. The challenge is to find the right balance between all these aspects. The fight against alien invasive insect pests of plants in the urban environment often affects varied sectors of the economy, landscape gardening, public health, and ecology. This paper focuses on the evolution of the red palm weevil in San Benedetto del Tronto, a coastal urban area in central Italy. We investigated the evolution of this insect pest of palm trees in the 2013–2020 period, considering both the effectiveness of the chemicals used and their potentially harmful effects. With a multidisciplinary approach, we carried out a spatio-temporal analysis of the extent and mode of pest spread over time using historical aerial photos, freely available remote sensing images, and field surveys integrated in a GIS environment. We also assessed the toxicity risk associated with the chemicals used to protect the palms from the red weevil. The fight against this weevil is now concentrated in specific areas such as parks, roads, villas, hotels, farmhouses, and nurseries. The preventive chemical treatments applied are very effective in preserving the palms, but they show a toxic potential for all organisms. We discuss current local management of this pest, focusing on several aspects involved in the fight against this beetle in an urban area. [ABSTRACT FROM AUTHOR]

Drawing upon the debates on 'suburbanisms' and 'arrival space', this article explores the complexities for welfare governance in multiethnic peripheries. The paper bridges two themes of the contemporary 'suburban century': the intensified global migration flows and the peripheral condition of suburbs worldwide; the work refers to the Municipality of Pioltello, a multiethnic suburban area in Milan's region. This double-sided perspective reveals governance dynamics, here discussed through the concept of 'welfare offloading'. In the observed neighborhood, governmental complexities disclose profound interdependencies with the region's urban core and across municipalities; welfare tensions are 'offloaded' from the central core to peripheral regions.

This paper investigates whether urbanization plays a role in determining the importance of each happiness domain on overall happiness. The analysis focuses on Italy. We exploit a multilevel model to consider regional heterogeneity in happiness determinants. We first verify whether a direct effect of urbanization exists on each specific components of happiness, as well as on overall happiness. Consistent with the findings in the literature, happiness decreases with urbanization. In the analysis of the mediating role, we find that the importance of satisfaction family explains more overall happiness in urban areas. On the contrary, satisfaction with health, friendships and environment gain more weight in rural areas. [ABSTRACT FROM AUTHOR]

This work addresses the relationship between the Italian city-making process following Unification (1861) and the development of military settlements up to the 1920s. The hypothesis presented here is that the building of military settlements and the redevelopment of spaces with new functions, arguably, shaped Italian cities over this period by implementing urban renewal processes and city expansion. Through my analysis, I claim that defence planning had an amenable effect upon the decision-making process of urban planning schemes. In addition, this paper claims that this process has impacted the location of military settlements in ways that boosted the economic and urban images of the city. I do this through a detailed case study of Milan's parade ground. Here, I found that the parade ground dismantling and relocation from the urban centre towards the periphery happened twice, relied on a specific narrative, and was catalysed by two mega-events. I demonstrate that defence planning plays a secondary role in boosting these operations aimed both at replacing military settlements with newly emerging functions and displacing the unwanted functions in the periphery.

Mapping urban areas from space is a complex task involving the definition of what should be considered as part of an urban agglomerate beyond the built-up features, thus modelling the transition of a city into the surrounding landscape. In this paper, a new technique to map urban areas using multitemporal synthetic aperture radar data is presented. The proposed methodology exploits innovative RGB composites in combination with self-organizing map (SOM) clustering and object-based image analysis. In particular, the clustered product is used to extract a coarse urban area map, which is then refined using object-based processing. In this phase, Delaunay triangulation and the spatial relationship between the identified urban regions are used to model the urban–rural gradient between a city and the surrounding landscape. The technique has been tested in different scenarios representative of structurally different cities in Italy and Germany. The quality of the obtained products is assessed by comparison with the Urban Atlas of the European Environmental Agency, showing good agreement with the adopted reference data despite their different taxonomies.

The present paper further develops a coastal vulnerability index formulation (CVI) previously proposed by the authors by integrating a new variable and redefining three variables to improve the suitability of the index for low-lying coasts. Eleven variables are divided into three typological groups: geological, hydro-physical process and vegetation. The geological variables are: geomorphology, shoreline erosion/accretion rates, coastal slope, emerged beach width, and dune. The hydro-physical process group includes: river discharge, sea-level change, mean significant wave height and mean tide range. The vegetation variables are: vegetation behind the back-beach and coverage of Posidonia oceanica. The index was applied to a stretch of the Ionian coast in the province of Crotone in the Calabria region (Southern Italy), and a vulnerability map was produced. A geography information system (GIS) platform was used to better process the data. For the case study area, the most influential variables are shoreline erosion/accretion rates, coastal slope, emerged beach width, dune, vegetation behind the back-beach, and coverage of Posidonia oceanica. The most vulnerable transects are those near urban areas characterized by the absence of dunes and vegetation. Statistical and sensitivity analyses were performed, and the proposed CVI was compared with the previous formulation proposed by the authors and with two other CVI methods present in the literature.

REINFORCED concrete buildings , *CITIES & towns - Abstract
The paper presents an analytical-mechanical based procedure to estimate the seismic overall fragility of existing reinforced concrete building portfolios in town compartments, as reduced areas of a municipality. The proposed methodology is based on two main concepts: (a) to consider all typological parameters characterizing the entire set of buildings located in a certain urban area and their variability through an analytical procedure; (b) to employ a mechanical approach by means of ideal numerical models to estimate the safety level of the focused sample of buildings. Hence, the methodology allows to compute seismic overall fragility curves, obtained by using laws of total variance and expectation and weighing factors proportional to the probability of having a certain configuration of typological parameters with determined values. To test the proposed procedure, some town compartments of the municipality of Bisceglie, Puglia, Southern Italy, were investigated by firstly identifying the most recurrent typological features exploiting multisource data, after by elaborating an extensive campaign of modelling and analysis on different ideal buildings (herein named realizations) and finally by computing fragility curves for each realization and for the set of ideal buildings. The results show overall fragilities curves for the investigated town compartments, which are obtained in a different way from the existing procedures, by avoiding an a-priori selection of one or more index buildings to represent the specific building portfolio and the definition of a specific building taxonomy.

Mountain communities face the threat of depopulation, as residents age or move to large cities in the lowland. This issue is pressing for Italy, where a large portion of the territory is mountainous and the overall population is rapidly aging. This paper analyses whether the autonomous status of a region affects the demographic dynamics of its mountain areas. The question is currently being fiercely debated in Italy, with border municipalities seeking to switch region in pursuit of perceived benefits, mainly in the form of the direct management of a larger portion of taxes. The analysis relies on an adjacency‐based estimation approach, including spatial regression discontinuity techniques, to compare population changes in mountain areas randomly selected from Northern Italian regions with special statutes versus neighboring regions without special statute. Measuring population changes in the 2000s shows a significant difference in the demographic dynamics in border regions, with areas in autonomous regions experiencing more favorable population dynamics. Our hypothesis is that fiscal autonomy contributes to sustainable local development and the survival of mountain communities. [ABSTRACT FROM AUTHOR]

On 27–28 July 2019, in a catchment of the Mt. Amiata area (Italy), an extreme rainfall induced a debris flow, which caused a channeled erosive process just upstream of the Abbadia San Salvatore village, the obstruction of a culvert at the entrance to the urban area, and the subsequent flooding of the village. In this paper, we present the back analysis of this event. The complexity of this case study is due to several peculiar characteristics, but above all, to the clogging of the culvert, a phenomenon difficult to simulate numerically. The methodology used for the reconstruction of the event is based on a multidisciplinary approach. A geological field investigation was carried out to characterize the catchment and assess the availability of debris. Then, a cascade of numerical models was employed to reconstruct the debris flow: the FLO-2D software was used to model the runoff along the hydrographic network while the mobile-bed debris flow TRENT2D model, available through the WEEZARD system, was used to quantify both the erosion and deposition processes that occurred during the event. To simulate the culvert clogging, a novel modelling procedure was developed and applied. Despite the challenging framework, the results, in terms of debris volume, erosion rates, deposition area, and timing of the culvert obstruction, agree reasonably well with the observed data. It is worth noticing that these results were obtained mainly using parameters set a priori, namely calibrated on a physical basis. This proves that the proposed methodology is robust and effective, with good predictive capability. Therefore, it may be considered, according to the European Union (EU) Flood Directive, an "appropriate practice and the best available technology that does not imply excessive costs" to support predictive hazard mapping of situations as the one here considered.

Does the settling of foreigners cause a rise in anti‐immigrant sentiment due to resource competition? Or do direct interactions lead to more respectful relations? And what if one also considers the settlement of foreigners in neighbouring municipalities? Applying an instrumental variable approach to variables collected at the Italian municipality level and including neighbouring areas, this paper aims to answer these questions by considering the vote for the Lega party in 2019 European parliamentary election as a proxy for the anti‐immigration sentiment. Our results point out that, once controlling for most socio‐economic variables and remoteness, a larger presence of foreigners within the municipality reduces the vote for the Lega. In contrast, the presence of immigrants in the neighbouring municipalities does not show a significant effect. [ABSTRACT FROM AUTHOR]

The scientific community has been studying for some time a measure capable of quantifying and monitoring the well-being of the population in the territories; this measure cannot be represented exclusively by economic components but also by dimensions that represent different domains of a mainly demographic-social nature. This paper aims to consider well-being from a multidimensional point of view and measure it for the 7983 Italian municipalities in order to highlight differences and similarities. To go down to such a fine territorial detail, it was necessary to use indicators implemented by administrative sources collected in a recently published portal. The application of composite indices allows a one-dimensional measurement that makes a complex phenomenon such as well-being more readable. From a territorial point of view, moreover, the work aims to overcome the administrative division already criticized in literature because it does not allow a reading corresponding to the real behaviors and lifestyles of citizens, embracing a classification more appropriate to the objective of the study. Since the elementary indicators taken into consideration are in some way influenced by reasons of proximity and/or territorial conformation, it was decided to use the classification in Ecoregions of Italy to assess whether the well-being, within the same municipality, "moves" in relation to the municipalities ecologically homogeneous. The results of the analyses present numerous aspects of originality in which the Ecoregions draw an interesting geography of the country. [ABSTRACT FROM AUTHOR]

Energy retrofitting of residential buildings is considered a challenge to be tackled not only at building level, but also at urban scale, to give a stronger impulse for a concrete transition towards climate neutrality. This paper presents an easy-to-use analysis method based on the elaboration and scaling-up of data collected through the energy performance certificates (EPCs) to identify different urban energy zones distinguished by their energy performance index. This method is therefore conceived for better informing urban planning decisions, thus boosting more effective energy-sensitive urban planning strategies and eventually to foresee dedicated financial instruments to act in the more energy demanding areas of the city, establishing priorities for integrated strategies. This analytical method has been applied and tested in one municipality in the Emilia-Romagna region, Italy, where the recent urban planning law is pushing municipalities towards the development of urban planning strategies oriented to drastically improve the energy efficiency of the existing building stock. Results show that only a small number of areas manage to reach a good performance with fairly low levels of energy performance index, with the most critical situation found in the most central areas of the capital and in the hamlets. • Easy-to-use method for assessing energy performance of residential building at urban scale is proposed • Method based on data easily available for local authorities, like energy performance certificates (EPCs) and urban morphology • The method supports urban planners in municipalities in taking more targeted decisions for improving energy efficiency • The main output of the method is the definition of an energy performance index (EPI) for different urban contexts • EPI allows to wisely balance economic incentives, identifying areas where multi-purpose interventions are recommended [ABSTRACT FROM AUTHOR]

Starting on 24th August 2016, Central Italy was struck by a six-month earthquake sequence that caused 303 victims and extensive major damages to urban areas and infrastructures, in some cases entire villages needed complete rebuilding. In this paper we present a map that portrays the overall susceptibility to multiple landslide types and the exposure to landslides of the rural-urban areas of the Castelsantangelo sul Nera Municipality, a typical village of the central Italian Apennine. The map is based on a procedure that ingests geomorphological data and models and groups the individual landslide susceptibility maps in a joint susceptibility and exposure map based on expert-defined criteria. The procedure has been applied to built-up and to undeveloped areas to highlight their exposure and was used as a tool for planning post-seismic reconstruction. We advise that such maps are used also as basic tool for ordinary urban planning. [ABSTRACT FROM AUTHOR]

The paper describes the multitemporal landslide inventory map prepared for the urban areas of Motta Montecorvino and Volturino, two municipalities located in the Southern Apennines (Apulia Region, Italy). These territories show a high propensity to landslides of different types and magnitude, which periodically interfere with the anthropic structures and infrastructures. For the study area, the spatial and temporal distribution of landslides is detected for the period between 1954 and 2003, through the visual interpretation of multiple sets of black and white digital stereoscopic aerial photographs at different scales. The analysis reveals locally high frequency of landslide occurrence and built-up areas on existing landslides, either on the body or on the crown areas. In particular, we show that over the years new residential areas were developed despite the presence of large old mass movements. [ABSTRACT FROM AUTHOR]

Inclusive and equitable education and the promotion of lifelong learning opportunities for all are important targets in the 2030 Agenda for Sustainable Development. Deprivation in education, read also as deprivation of opportunities and rights i.e. health, culture, participation, social relations, referred to as educational poverty (EP), has attracted interest of researchers, which highlighted its complexities and consequences, such as being excluded from acquiring the skills needed to live in a world characterized by knowledge-based economy, rapidity and innovation. In the last few years, the Italian National Statistical Institute started to measure it by a multidimensional index, the composite educational poverty index (EPI). The index is based on survey direct estimates, which are reliable only at regional (NUTS 2) level, while to monitor and contrast the phenomenon it is important to obtain information at a finer geographical level. In this paper small area estimation models are applied to the unidimensional indicators which compose the multidimensional EPI. The aim is to enhance the knowledge of the spatial distribution of EP at local level in Italy, separating urban and non urban areas and focusing on peripheries in Italian Regions, using DEGURBA classification in order to help the policy maker to address resources towards the areas where the phenomenon is strongly present.

The obligations arising from legislation and other instruments affect the macro-level decision-making related to the transition toward a circular economy (CE), which is a multifaceted topic since it tries to aggregate the interests of different stakeholders. In this context, this paper aims to analyse the current policies, strategies and initiatives related to the CE transition from a multicriteria perspective and under the lens of NIT (New Institutional Theory). This is the first approach that analyses which CE strategies and related practices boost the transition from a macro-level perspective, using a multicriteria method and considering developed and emerging economies. For this reason, this paper can be helpful for researchers and practitioners involved in implementing strategy and policymaking aimed at the transition toward a CE. It also contributes to the discussion on the global transition to the CE by identifying differences and similarities between countries. The proposed methodology has been applied to compare the realities in Italy and Brazil. The perceptions of several stakeholders from the two countries have been gathered through a questionnaire to evaluate numerous strategies against several social, environmental, economic, and technical criteria. The main results are: Italy presents a proactive behaviour, a higher level of institutionalisation, and a coercive isomorphism related to European regulations and strategies. In contrast, Brazil has reactive behaviour, a lower level of institutionalisation, and is impelled by mimetic isomorphism. Although it is possible to observe several advances in the last years in Brazil, the transition to a CE is still in the early stages compared to Italy. [Display omitted] • Transitioning to a new economic model is not a quick and straightforward process. • Transition requires changes in countries, regions, cities, supply chains and companies. • Some strategies and related practices have been adopted to enable the transition. • National legislation and Action Plans can boost the transition toward a circular economy. • In developing countries, the exploration of CE concept and its potential benefits has been rare.

In recent years, the presence of urban wildlife has increased in many cities around the world, with the consequent increase of human-animal relations. The city of Genoa (NW Italy) is a particularly complex case study where such phenomena are associated with rural depopulation of the surrounding countryside and spontaneous rewilding processes that have led several animal species to approach urban areas in search of new spaces. This paper deals with human-wildlife interactions in Genoa in relation to the geography of the city by way of a survey circulated throughout Genoa. Drawing from survey data, the research investigates residents' perceptions and understanding of urban wildlife in relation to their area of residency with a focus on wild boars. People's responses show that some areas of the city have a higher level of interaction with wildlife, and this partly affects the way in which such phenomena are perceived and tolerated by the population. In addition, the results show that there is no clear opposition towards urban wildlife and that people are concerned about sustainable forms of urban planning to the benefit of both residents and wildlife. • Rewilding processes involve both rural and urban areas of Liguria (NW Italy). • In recent times city of Genoa (NW Italy) has seen a progressive increase of wildlife. • Intensity of human-animal interactions varies in relation to people's area of residency. • People are concerned about public safety and good quality of urban environments but also animal welfare.

This paper investigates whether the gender of elected politicians affects the performance of Italian local governments in providing equitable and sustainable well-being to citizens. In fact, Italy was the first country in the European Union to include citizens' well-being objectives in economic planning. We use data on more than 6000 Italian municipalities for two years to investigate the relationship between gender representation at three bodies of local government with measures of socio-economic and environmental sustainability and find that larger representation of women in municipal leadership, executive and council bodies is significantly associated with improved municipal well-being. These results are also confirmed by accounting for endogenous issues, by adopting an extended definition of well-being and other robustness checks. Differences among northern and southern regions emerge with regard to the effects of incumbent female politicians. Other heterogeneous impacts are unclear or less marked. • A Wroclaw composite index of well-being is constructed at municipal level. • Gender quotas is used as instrumental variable in 2SLS regressions. • A larger share of women in municipal political bodies improves citizen's well-being. • Heterogeneity effects are detected among North vs. Center-South macro-regions.

The aim of this paper is to ground gentrification processes within a broader urban transformation pattern and within a deeper historical account, taking an ordinary city into consideration: Turin, in the North West of Italy. The paper elaborates on qualitative data collected along a twenty year span, allowing reflection on different phases and dynamics of capital extraction across time. We will show that, problematically, gentrification was considered as a positive model by local authorities and that it was adopted as a reference by both private and public actors to generate local growth and to react to economic crises.

• Optimal design of multi-vector energy hubs in energy communities. • MILP model using a multi-objective function. • Application to a real case represented by a university campus. One of the main ways to reach the important targets of the European Commission in the energy field set by 2030 is to implement sustainable energy systems to cover electrical and thermal energy demands, as well as transportation needs, in urban areas. In the aforesaid scenario, multi-vector energy hubs consist of installing small and medium size power plants, mainly fed by renewable sources, and charging infrastructures for electric vehicles in sustainable urban districts. The optimal design of such systems can be faced from different points of view and using different methods, one of the most adopted being the development of mathematical programming algorithms typically aimed to minimize global costs and emissions. The contribution of this paper is to propose an innovative methodology to optimally design a multi-vector energy hub able to supply electricity and thermal energy, for space heating and cooling, to a set of buildings within a sustainable district acting as a local energy community. The developed mixed integer linear programming model is characterized by very detailed models of the technologies and by a multi-objective function which is proposed to evaluate the impact of the optimal solution on global costs and emissions. The proposed mathematical model is very comprehensive as it involves a wide range of energy technologies with detailed modelling by considering the impact of external ambient conditions and energy vector temperature values on the plant conversion efficiency, thus showing high replicability potential in real contexts. In the case study, the model is applied to a university campus in the North of Italy. [ABSTRACT FROM AUTHOR]

This paper contributes to the critical literature that links greening initiatives with the risk of gentrification. As urban areas become greener and provide high quality amenities, they attract wealthier residents, thus channelling the benefits of greening to a few. Most existing research has analysed the results of greening initiatives once they have been completed. This article explores green gentrification as a form of strategic action, by analysing the emerging Green Tree Strategy (GTS) for Porto Marghera, Italy. This area has undergone historical greening initiatives, beginning with the "garden city" of Enebezeer Howard (1902). The GTS is the newest green regeneration initiative in Porto Marghera. The data were collected via semi-structured interviews and through an online social network survey. The results show that the GTS has a clear ideological core – built around a new strategy of perception – but also that its appeal can be challenged in terms of industrial and employment displacement. The support for the GTS is fragmented and lacks consensus in Porto Marghera. However, if local actors are to successfully resist further attempts at green gentrification, they likely need to build an alternative vision, organized around a balanced development between green infrastructures and social inclusiveness. • Sustainability and greening initiatives in cities often lead to gentrification. • The Green Tree Strategy (GTS) is an early stage greening initiative proposed for Porto Marghera, Italy. • We explore the GTS as a form of strategic action, developing in a social movement like fashion. • Green gentrification is avoidable but resisting it requires an alternative conception of equitable greening.
